endocrine/exocrine glands
• mice exhibit biliary agenesis
• the ventral pancreas and biliary primordium do not develop into distinct structures unlike in control mice
• the common duct is replaced with pancreatic tissue
• at E18, here are decreased numbers of pituitary gland progenitor cells compared to wild-type, shown by proliferation assays
• at E18, pituitary gland is hypoplastic but morphologically normal
• the ventral pancreas and biliary primordium do not develop into distinct structures unlike in control mice

nervous system
• at E18, here are decreased numbers of pituitary gland progenitor cells compared to wild-type, shown by proliferation assays
• at E18, pituitary gland is hypoplastic but morphologically normal

cellular
• cultured neural precursor cells have an impaired ability to produce astrocytes

liver/biliary system
• mice exhibit biliary agenesis
• the ventral pancreas and biliary primordium do not develop into distinct structures unlike in control mice
